Air Purifiers Consumer Reports

If you are considering buying an air purifier either for yourself or as a gift for a special occasion then it is important that you pay attention to what others have experienced through purchase of the product you are considering. In this way, you can make a wise choice when it comes to the best purchase of the purifier. The quality and the durability of the item needs to be researched and also the type of customer service that the company offers, will be high on your list of priorities.

When considering the purchase of an air purifier you should know that few can be compared directly unless you want to buy a comprehensive product that will be the most versatile and that will filter a wide range of materials out of the air that we breathe. There are many on the market that are specific for a certain job but are not suitable for others. In the health conscious age in which we presently live you should know that to get the very best air purifier to filter and clean as much of the air we breathe as possible will require the purchase of a more expensive model which will have clearly superior features. If you are only interested in removing animal hair or the smell of smoke from the air you breathe then you can pick up very economical air purifiers for use but they will not purify the air as a comprehensive air purifier would.

In this day and age with pollution, metal absorption, molds, pathogens and allergies; it seems vital for our health to breathe clean air. If this is true then buying a great purifier as a wedding gift would be a great expression of love and would bring lasting results. In this regard, it might save someone from dying if they have protection from a pandemic virus. Some of these are expensive, but often make an ideal gift for a group of people so that the cost can be shared.

There are many types of air purifiers which I will talk about and provide the best gift buying selections for and then wrap up this article by giving my ultimate recommendation.

Best Room Air Purifiers

What is the best air purifier for home? If the purpose is to filter any pathogens out of the air as part of the air purification process along with all other contaminants, then Ultra violet light removes potentially harmful viruses, bacteria and pathogens from your home by passing the air through an ultraviolet light chamber which will kill 99.9% of mold spores and will also remove dust and other contaminants from the air. The best air purifiers will have ultraviolet light as this will kill viruses.

These units will also have an ionic generator. These act to charge free flowing particles in the air so that they will be attracted to a collector so that the charged particles are trapped and do not recirculate in the air that you breathe. Of course, the more foreign objects such as mold, pet hair, dust and other contaminants that are removed from the air that you breathe; the better you will be able to breathe and enjoy a healthy life style. Some units produce ozone because it too, can react with other free floating molecules which purifies the air by removing mold, viruses, bacteria, odors and air-borne particles from the air resulting in a clean smelling mountain air fresh room.

Some of these units come with Hepa filters. These filters are impressive in that they can remove many of the contaminants in the air simply by forcing the air through the filter. If you are to maintain the integrity of the unit and its ability to filter out the contaminants and pathogens from the air you breathe; it is important that you follow a regular maintenance schedule. These filters are only effective if changed regularly but you can use medical-grade Hepa filters for superior results.

I will now share the results of consumer reports on the better quality comprehensive units that can be purchased.

Comments from customers:

Loved the fact that you don’t even know the product is in the room. We find the need to dust and clean the room is reduced. Customer service is good. They efficiently take care of any needs. Although we only have one, I’m considering buying one for our second floor.

Over a year after I purchased this air purifier I developed an issue. It turned out that the issue was of my own making, but despite the fact That I hadn’t purchased the protection their representative sent me a replacement unit at no charge making me an extremely satisfied and happy customer.

I bought this because the previous owner of my house was a heavy smoker. Work great. I have no way of measuring some of the claims, like the sanitizer function, but it does reduce the amount of dust and odors in the house.

This unit is a comprehensive unit that is easy to use and in sleep mode is very quiet. The only thing it lacks is an ozone generator, although some people are allergic to ozone. The customer service is rated as very superior and it comes with a fully replaceable promise if you are not satisfied. This in itself is of great value.

Customer comments:

Really like all the features. Sleep + Auto mode is very quiet compared to the other versions. Ionization + UV seems to be working and keeping the air quality in good shape. Easy to read air quality monitor is really nice to have and only spins up higher when it is needed instead of always being on a specific speed. My only complaint at the moment is that the O filter that is used is not available on Amazon yet.

Claims to UV irradiation are based in reality, as the unit has a consumer replaceable UV bulb in the base.

Clean Air Delivery Rate” for various particulate contaminates, are certified by something called the AHAM (Association of Home Appliance Manufacturers), an industry group with an office in Washington, D.C. which claims to have been around since 1967. It has been certified as supplying the rates specified.

“Carbon” pre-filters in replacement four packs are advertised in the instruction book, and they claim “activated carbon”; yet it appears to be a black plastic mesh, showing no evidence of entrapped carbon particles.

Customers rate this unit very highly and indicate they are satisfied.

Customer comments:

I purchased a Levoit Air Purifier model 300 earlier this year in hopes that it would help reduce the smell of our pets who like to stay in our large open basement. I honestly did not think it would work and had already decided if it didn’t, I would return it. Much to my surprise, not only did it work but it worked well and we ended up ordering a second one for the office.

Jumping forward to Amazon Prime Day 2, Levoit had their wonder air purifiers on sale and I decided to buy the large (and expensive) 600 model because it could cover up to 1500 SF. Let me tell you, even with the astronomical price I have not been disappointed. The big 600 is not a small unit at all but it does a great job of purifying our first floor open floor plan that is > 1500+. The auto fan setting is amazing and turns on and off based on the quality of the air and is color coded to let you know. I briefly mentioned that downloadable app. It’s very cool that you could control the 600 from my smartphone or from Alexa. But I keep it in auto mode and never have to open the app.

This is a highly rated unit that seems to give amazing results even when purifying the air in large rooms.

Customer comment

It was summer in Seattle and the blooming things were exploding with delight, unleashing a blanket of pollen on the city and providing job security for the makers of Sudafed. I’d grown weary of sneezing myself to sleep at night and of constantly vacuuming up dust. It was the summer I turned to air purification for my salvation.

I bought the Alen 45i on the recommendation of Consumer Reports. After a few initial hours on turbo, it settled into a quiet cycle on auto mode and I haven’t had to touch it since. Pretty quickly, my dust level was significantly diminished and I was sleeping better. I found that when I walked downstairs in the morning I would immediately start sneezing, so I ended up purchasing the larger 75i for my living room (probably overkill for my space; it’s a gigantic beast). Both units are extremely quiet unless they’re on turbo — but they call it turbo for a reason — and they’re super-easy to set up and use. They also look nice, and I like that you can turn off the display light on the 45i so it doesn’t cast unnecessary light in the bedroom at night.

So far so good on the filter, though I haven’t had it long enough to say whether it’s as long-lasting as claimed. Assuming it continues to perform I think it’s worth the investment for cleaner air and better sleep.

I love everything about this unit. It was simple and easy to get it ready to use. It works great and could tell right away the difference in the air quality. I love the filter features and economical aspect of the unit. Very nice size, smooth look, quiet running and overall quality of this unit. I would highly recommend buying this for those who have allergies, illness and any respiratory issues. It really works just as described!! Definitely would purchase again!

This is our second purchase of the NUWAVE Oxypure filter. Yes, it’s expensive but the results are worth every penny. We live in a high pollen area and we were experiencing constant sinus headaches. After our first purchase of the unit, we noticed a gradual decline of the sinus headaches and allergic reactions in general. That sold us right there! Hence, here we go again with another unit in another part of the house. NUWAVE makes these very easy to maintain with a multiple filter system (2 that are washable). We discovered that this company is very proactive with customer service and they want to make certain that all equipment they sell functions properly. This is one of the few products that I can highly recommend.

This is a quality unit with great customer reviews.


In conclusion, the air purifiers all have impressive ratings and will make excellent choices. Consumer ratings of these products are impressive and one has the highest rating for customer service. The consumers report great experiences with use of these products and give then exceptional ratings. For healthy air and an extra special wedding or anniversary present; these are exceptional.
